The idea that Japan can improve its security without dropping a long-standing ban on aiding friendly countries under attack is a miracle that just won¡¯t happen, the acting head of an advisory panel to Prime Minister Shinzo Abe said.

Abe has made clear that he wants to lift the ban on collective self-defense to bolster security ties with the United States as China expands its military and North Korea develops its nuclear capabilities.

The lifting of the ban would be a major turning point for the military, which has not engaged in combat since its defeat in World War II under a U.S.-drafted pacifist charter.
